Core Daily Management: Exercise, Weight, and Devices

While it is common to focus on medications or surgeries, the most highly recommended treatments for osteoarthritis (OA) are lifestyle-based. Major medical organizations, including the American College of Rheumatology (ACR) and the Osteoarthritis Research Society International (OARSI), identify education and exercise as core treatments for everyone with OA. For those who are overweight, weight management is also a critical foundational pillar ^[1][2].

These are not just “tips”—they are the bedrock of evidence-based care ^[3]. While they cannot reverse OA or regrow cartilage, they are highly effective at improving pain, strength, and function ^[4].

Movement as Medicine

Exercise is the most effective non-surgical way to reduce OA pain and improve function ^[2]. Appropriate movement helps circulate joint fluid and strengthens the muscles that act as shock absorbers. A complete program usually includes three types of activity:

• Strengthening: Focusing on the muscles around the affected joint (like the quadriceps for the knee) helps take the load off the joint itself ^[1].
• Aerobic Exercise: Low-impact activities like walking, cycling, or aquatic exercise improve your overall fitness and cardiovascular health ^[2].
• Balance and Coordination: Also called neuromuscular exercise, these movements help your brain and muscles work together to stabilize the joint, which is especially important if you feel “unsteady” or like your joint might give way ^[1][2].

Pacing Your Activity: The key to success is “dosing.” Your exercise should be tailored to your current ability and slowly increased over time. Mild, temporary discomfort during or after activity is generally acceptable and does not mean you are damaging the joint. However, if a movement causes a sharp increase in pain, marked swelling, or a sustained flare that lasts more than 24 hours, the “dose” was likely too high and should be adjusted ^[1]. If you have instability or severe pain, working with a physical therapist is strongly recommended.

The Impact of Weight Management

Weight management is recommended specifically for people with OA who are overweight or obese. The benefits follow a dose-response relationship, meaning the more excess weight you lose, the more your symptoms tend to improve ^[5][6].

• The 5% to 10% Goal: Research shows that losing just 5% to 10% of your body weight can lead to significant improvements in pain and physical function ^[7][5].
• Why it Works: Weight loss reduces the physical pressure on weight-bearing joints (like the hips and knees) and decreases the amount of inflammatory chemicals released by fat tissue into your bloodstream ^[8][9].
• Preserving Muscle: It is important to combine any weight loss efforts with strengthening exercises. Losing weight without exercise can lead to muscle loss, which decreases the support around your joint.

Assistive Devices and Bracing

If exercise and weight management aren’t enough to keep you active, specialized devices can help “unload” the joint or provide stability.

• Walking Aids: Using a cane in the hand opposite to your painful hip or knee can reduce the load on that joint by up to 25% ^[3][10]. It is important to have a professional (like a physical therapist) ensure the cane is the correct height to avoid back or wrist strain.
• Knee Braces:
  • Unloader Braces: These are specialized “tibiofemoral” braces designed to shift weight away from the damaged side of the knee to the healthier side ^[1][11].
  • Patellofemoral Braces: These are often softer sleeves designed to help the kneecap track more comfortably ^[12].
• Hand Orthoses: For OA at the base of the thumb (the CMC joint), a properly fitted thumb-spica splint or orthosis is strongly recommended. These stabilize the thumb during pinching and gripping tasks, which can significantly reduce daily pain ^[1][13].

While these devices can be very helpful, they work best when used alongside a strengthening program, as relying on a brace alone can sometimes lead to muscle weakness over time ^[14][15].
